BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates to the power hydrostatic and electric transmissions association, specifically to a system of internal combustion engine, pump with hydraulic motor and power electric units combination, which are used for high efficiency automotive driving.

2. Background of the Invention

The widespread hydrostatic transmission is used to drive wheels and working equipment of widely known machinery—mountainous, construction, agricultural, transportation automotive and other heavy equipment. Also widely know hybrid cars with engine and power electric units combination.

System engine-pump are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

By way of example, U.S. Pat. No. 5,261,797 to Christenson (1993), U.S. Pat. No. 5,556,262 to Achten et al. (1996), U.S. Pat. No. 5,616,010 to Sawyer (1997), U.S. Pat. No. 6,293,231 to Valentin (2001), U.S. Pat. No. 7,011,051 to the same inventor Epshteyn (2006), U.S. patent application “Universal hybrid engine, compressor and pump and method of operation” Ser. No. 11/110,109 (filing date Apr. 20, 2005) to the same inventor Epshteyn and U.S. patent application “Monocylindrical hybrid two-cycle engine, compressor and pump, and method of operation” Ser. No. 11/373,793 (filing date Mar. 10, 2006) to the same inventor Epshteyn.

While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe the monocylindrical hybrid powertrain and method of operation for providing compact design, increased efficiency and specific power while minimizing the fuel consumption.

The modern hydrostatic transmission has the following disadvantages:

-   -   (a) The pump and hydrostatic motor association requires hoses or         pipes and no provides compact and inexpensive solid mono-block         design of the progressive hydrostatic transmission.     -   (b) The hybrid two-cycle engine, compressor and pump synchronize         mechanism is complicated and expensive.     -   (c) The hybrid two-cycle engine, compressor and pump system no         allow the stand-by electric energy accumulation by means of         plug-in.     -   (d) The hybrid two-cycle engine, compressor and pump hydraulic         system no allow the engine capacity decrease and simultaneously         to remain automotive acceleration.     -   (e) The hybrid two-cycle engine, compressor and pump hydraulic         system no allow the pneumohydraulic accumulator energy directly         utilization for the engine piston return stroke.

OBJECTS AND ADVANTAGES

Therefore, it can be appreciated that there exists a continuing need for a new and improved monocylindrical hybrid powertrain providing joint operation of the progressive hydrostatic transmission and electric transmission having better specific data than widespread automotive engine and automatic transmission.

The present invention substantially fulfills these needs.

The objectives and advantages of the present invention are:

-   -   (a) to provide compact, inexpensive solid mono-block design of         the hydrostatic transmission by means of the valve plate         fastened simultaneously to the engine cylinder and hydrostatic         motor.     -   (b) to provide hybrid engine, compressor and pump synchronize         mechanism simple and inexpensive by means of the axial rods and         compensate pistons use in capacity of linear motor pushing the         synchronize mechanism against the swash plate.     -   (c) to provide electric stand-by energy accumulation and the         plug-in utilization by means of the hydrostatic motor and the         electric motor association.     -   (d) to provide the engine capacity decrease and simultaneously         to remain the vehicle acceleration by means of simultaneously         the stand-by electric and pneumohydraulic accumulator energy         utilization.     -   (e) to provide the engine piston return stroke by means of the         pneumohydraulic accumulator energy actuate the stabilizer motor.

The three-way second hydraulic distributor has a first line 388 (FIG. 18) connected to the stabilizer motor inlet and by line 392 to the hydrostatic motor 44 outlet, second line 394 coupled with the spin-valve 178 circular slot 184 (FIG. 5, FIG. 6) and third line 396 (FIG. 18) connected to the pneumohydraulic accumulator.

The spin-valve 178 one autonomous slot 186 (FIG. 5, FIG. 6) coupled with the pneumohydraulic accumulator by line 398 (FIG. 18) and second autonomous slot 188 (FIG. 5, FIG. 6) coupled with the replenishing pump outlet by line 384 (FIG. 18).

The starter pump 402 by means of the pedal 404 provides an opportunity to increase the pneumohydraulic accumulator fluid pressure with muscle efforts in the emergency case.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.

Description of Operation.

The hybrid has starting, restarting, idling, work mode of operation and pneumohydraulic accumulator (PHA) charging by means of engine power operation and by muscle efforts. Also the hybrid provides by means of the stand-by energy and the hydrostatic motor and electric motor association automotive start acceleration, automotive regenerative breaking and automotive emergency ahead and reverse movement.

The operator initiates the start. Switching from start to idle mode is automatic. The work mode is initiated automatically after the accelerator pedal (not illustrated) is depressed. The PHA charging by mean of engine can to occur during the automotive parking automatically. Also the hybrid can to provide PHA charging during the automotive deceleration that is regenerative breaking.

Engine Start.

The operator switches start by key ignition (not illustrated) and the solenoid 366 switches distributor 364 to the engine start (FIG. 18, FIG. 18A, FIG. 18B). During the starting process pressurized fluid goes from the PHA 328 via distributor 358 and lines 344, 378 to the pump inlet and via distributor 364 and lines 344, 388 to the stabilizer motor inlet. The pressurized fluid activates the stabilizer motor and goes to the replenishing system accumulator 72 along line 386 from the stabilizer motor outlet independent of the engine piston direction movement. Simultaneously pressurized fluid in the pump inlet actuates engine piston return stroke.

Thus PHA fluid supply actuated the stabilizer motor motion during the engine piston downwards stroke and during engine piston return stroke the PHA fluid supply actuated simultaneously the stabilizer motor motion and the pump plunger motion occurs in the capacity of linear hydraulic motor.

Because compensate piston ends fluidly connected with an axial canal located diametrically opposite to said pump chamber canal high pressure fluid from PHA actuated in turn an axial rods and compensate piston ends. So during the engine start occurs permanent pushing of an axial rods against the swash plate.

The stabilizer motor by pistons 154 (FIG. 9) interacting with swash plate 52 rotates the rotor and actuate the plunger with engine piston to top end position. The engine piston compresses the air in the combustion chamber, and conventional fuel injection (not illustrated) initiates the power stroke of the engine.

The rotor by conic reducer, sprocket wheels and chain activate the engine camshaft, which by means of the pulley with belt actuate conventional accessory units: cooling system pump, electric system generator, steering pump (not illustrated).

During one half revolution, while the pump chamber canal connects with the pump inlet slot, the outlet slot is closed. During the second half revolution, while the rotor canal connects with the pump outlet slot, the inlet slot is closed. Such sequences occur in the all the operating modes.

So operates a high-power hydraulic starter. The starter is able to fast start and restart of the single cylinder engine.

The high pressurized fluid enables a quiet starting process to occur, and also enables an engine to shut down at every red traffic light with decreased fuel consumption. This is very valuable in particular for automobiles' hydrostatic transmission.

If the fluid pressure in the PHA is not sufficient the pump 402 (FIG. 18) with the pedal 404 provide an opportunity to increase fluid pressure with muscle efforts. Thus, the hydraulic system enables one to start and restart engine independent of any external energy sources such as an electric battery, for example, thus providing the autonomous work of a hybrid and engine start, irrespective of parking time.

Idling Mode.

The rotor angular velocity increases after the start up. A speed sensor (not illustrated) switches the solenoid 362 (FIG. 18, FIG. 18C, FIG. 18D) and the distributor 358 connects PHA in parallel to the pump outlet and hydrostatic motor 44 inlet by lines 344, 374, 372 and check valve 376. The distributor 364 remains the engine start position. The engine automatically switches from starting mode to the idling mode. The hydrostatic motor shaft braked during the idling, which occurs by minimum displacement volume engine and pump.

During the engine piston downwards motion (FIG. 18C) the fluid goes from the pump outlet via the line 374 and the pump inlet line 378, is closed. During the engine piston upwards motion (FIG. 18D) the fluid goes to the pump inlet and the pump outlet is closed.

The pump displacement volume approximately equal the stabilizer motor displacement volume. During the half rotor revolution (the engine piston downwards motion) the pump supply is the whole pump displacement volume but the stabilizer motor intake is only half of the pump volume. Because the pump coupled in parallel with PHA and with stabilizer motor by lines 374, 372, 344, 388 the pump's fluid volume surplus entered the PHA (FIG. 18C). During the next half rotor revolution (the engine piston upwards motion) this fluid volume surplus goes from the PHA to the stabilizer motor inlet via lines 344 and 388 (FIG. 18D).

So occurs the engine piston return stroke by means of the stabilizer motor used the PHA energy and actuated the hybrid motion. The stabilizer motor actuated the hybrid motion independent of the engine piston direction movement.

The energy of combustion pressure is transmitted to the piston-plunger during its movement from the top end position (TEP) to the bottom end position (BEP). This process is illustrated in FIG. 20A. The engine valves 104, 102 are closed. The compressor intake valve 124 is closed and the output valve 126 is open.

The sliding holder 246 and hub 122 (FIG. 10) is actually a bearing because the compressor piston is not rotating. The crossbar 236 and plunger 156 (FIG. 10) is actually a bearing because the pump plunger is not rotating.

Because compensate piston ends fluidly connected with an axial canal located diametrically opposite to said pump chamber canal high pressure fluid from pneumohydraulic accumulator actuated in turn an axial rods and compensate piston ends. So during the idling occurs permanent pushing said axial rods against said swash plate.

Thus the synchronize mechanism provides the opposite movement of engine and compressor pistons. The rotor drives the engine camshaft by the conic reducer gearwheels 256, 258 (FIG. 3) sprocket wheels 264, 268 and chain 266 and simultaneously rotor rotates the lobes 134, 142 (FIG. 2, FIG. 15) activating the compressor intake valve 124 and output valve 126.

So the synchronize mechanism provides the engine and compressor valves with motion, with consequent performance in compliance with a two-stroke working cycle; and each engine piston stroke from TEP to BEP is a power stroke.

The movement of all components of the synchronize mechanism in oil within pump chamber provides high quality lubrication and increase the efficiency.

The compressor piston and axial rod have equal strokes. The lever gives the piston-plunger an increased stroke, in accordance with the lever ratio.

Thus the opposing movement of the compressor and the engine pistons allows the space under the engine piston to function as chamber of the compressor. This ensures, that the noise is decreased, because static energy is used, that is air pressure, instead of air high speed, i.e. kinetic energy as in a conventional blower. Because the pistons are moving in opposing directions, the engine piston becomes in essence a compressor piston. This results in direct energy transmission for air compression, and provides increased efficiency.

The opposing movement provides simple and high-quality balancing of the system because the compressor piston compensates for the inertial forces influencing the piston and plunger. This considerable decreases the vibration and determines the stationary connection of the engine cylinder and hydrostatic motor by valve plate. This forms hydrostatic transmission solid monoblock.

The pistons' opposing movement provides a compressor displacement volume greater than the volume of the engine, because it is formed by the superposition of the motions of the engine and compressor pistons. This increases air mass intake and specific power of the engine. The idling mode continues as long as the accelerator pedal is not depressed.

Work Mode.

The accelerator pedal (not illustrated) depression increases the rotor angular velocity and a speed sensor (not illustrated) switches off the solenoid 366 (FIG. 18, FIG. 18E, FIG. 18F). The distributor 364 switches to the neutral position and closes lines 388, 394, 396. The distributor 358 remains the engine idling position. Thus the hydraulic system automatically switches from idling to work mode if the accelerator pedal is depressed.

The FIGS. 20A, 20B, 20C, 20D illustrates the hybrid operating sequence during a single revolution of the rotor (two cycles of the engine).

The FIG. 20A shows the piston-plunger power stroke from TEP to BEP and simultaneously the compressor piston power stroke with motion in opposite directions. The engine valves 104, 102 are closed, the compressor output valve 126 is open and the intake valve 124 is closed. The pressurized fluid flow goes from the pump outlet via lines 374, 372 (FIG. 18, FIG. 18E) and check valve 376 to the hydrostatic motor 44 inlet and via lines 392, 388 to the stabilizer motor inlet. The pump and the stabilizer motor displacement volume approximately equal. During the half cycle the pump supply is equal the pump displacement volume but the stabilizer motor intake is only half of the pump volume because the pump and stabilizer motor coupled in series. The fluid volume surplus via distributor 358 and line 344 entered the PHA 328. During the next half cycle (FIG. 18F the engine piston upwards motion) this fluid volume surplus entered the motor 44 inlet from the PHA via lines 344, 372, check valve 376 and distributor 358. Diagrams in figures FIG. 19A, FIG. 19B, FIG. 19C show this process. The T is one cycle time. The Q (FIG. 19A) is supply of pump continues half cycle time, the PHA (FIG. 19B) half cycle time receives fluid from the pump and next half cycle time delivers fluid to the hydrostatic motor, the hydrostatic motor receives uniform fluid supply (FIG. 19C) during the whole cycle.

Simultaneously the fluid goes from hydraulic replenishing system via lines 384, 378 and distributor 358 to the pump inlet, provides necessary suction fluid pressure and provides return stroke of the engine piston. Thus occurs transforming the single pump plunger supply pulsation into uniform fluid flow feeding said hydrostatic motor during said engine power operation. The uniform fluid flow via hydrostatic motor determines the stabilizer motor and hydrostatic motor connection in series.

The hydrostatic motor smoothly operation occurs independent of the pump supply pulsation because the pump supply charges PHA and simultaneously actuates connecting in series hydrostatic motor and stabilizer motor during engine power stroke and during engine piston return stroke PHA fluid supply actuated the hybrid motion. This provides permanent pushing axial rods against the swash plate and allows use of one simple single cylinder hybrid instead of expensive, complicated and heavy multi-cylinder engine, compressor and a pump. Because direct energy transmission the engine piston return stroke occurs with minimum energy losses and minimum specific fuel consumption. Also this decreases weight, cost and installation space of the hybrid.

The energy of combustion pressure is transmitted to the piston-plunger during its movement from the TEP to the BEP during a half revolution of the rotor.

The greatest part of the power flow is the pump supply directly from the pump outlet to the motor.

The pump plunger fixed to the engine piston provides direct energy transmission. This allows use of one simple unit hybrid instead of two complicated and heavy regular units (an engine and a pump). Also the hybrid solves the problem of using reciprocating engine and compressor without a crankshaft or connecting rods. This increases efficiency and decreases fuel consumption.

The pump plunger disposition on the rotor's centerline allows a considerable increase in rotor speed rotation and transmission power in comparison with a conventional pump.

All these factors enable us to increase the pump power to equal the maximum engine power.

The second, and much smaller, part of the power flow uses the interaction of the underside of the engine piston with the compressor piston to compress air The compressor piston motion is provided by fluid pressure on the hub 122 in the pump chamber simultaneously with the pump power stroke, without cross forces. The air compression with direct energy transmission by means of the fluid pressure increases efficiency and decreases fuel consumption. The additional air cooling by the receiver water jacket 132 (FIG. 2) increases the engine thermal efficiency and decreases fuel consumption.

The third and smallest part of the power flow is transmitted to an engine and compressor valves and accessory units.

The location of the piston-plunger (inside the cylinder and simultaneously inside the hub 122) and the minimum magnitude of cross forces as it moves, allow the engine piston length to be minimized. The location of the compressor piston and the hub (simultaneously within the cylinder and the rotor) allows the compressor piston length to be minimized. This provides a compact design, minimizes piston mass and forces of inertia.

In work mode, the synchronize mechanism provides movement of the compressor piston and the rotation of the rotor, in synchronization with the piston-plunger movement, irrespective of the engine load or rate of acceleration.

Thus the power strokes of the engine, pump and compressor are taking place simultaneously, with direct energy transfer, without any intermediate mechanisms and without a cross force influence from the pistons or the plunger. This minimizes and simplifies the design, and increases the longevity and the efficiency of the hybrid.

In the hybrid, the weight and installation space are smaller than in the conventional system engine-pump thanks to the direct energy transmission.

The synchronize mechanism provides a two stroke working cycle; and each engine piston stroke from TEP to BEP is a power stroke. The piston-plunger in BEP and the compressor piston in TEP simultaneously complete their power stroke. The air is compressed in the receiver to maximum pressure.

The piston-plunger movement from BEP to TEP (FIG. 20B, FIG. 20C, FIG. 20D) occurs simultaneously with the compressor piston movement from TEP to BEP, during a half revolution of the rotor. The compressor intake valve 124 is open, the output valve 126 is closed and the air is sucked into the compressor chamber. Simultaneously the fluid goes to pump inlet from the hydraulic replenishing system

Because of its location on the side surface of the cylinder, the compressor intake valve diameter can be made much larger than the intake valve of a regular engine, with equal displacement volume. The intake air is cooler because it does not pass through the combustion chamber as with a conventional engine. This increases volumetric efficiency and air mass in the compressor chamber. Such joint factors improve the engine operation in all conditions and particular at low atmospheric pressure, for example, high above sea level.

The engine piston movement from BEP to TEP is comprised of three successive processes: combined clearing, joint compression, and finish compression (of the air in case of diesel, or of the mixture in case of gasoline engine) by the engine piston.

The combined clearing process is shown in the FIG. 20B.

There are three factors in the combined clearing process.

The valves 102, 104 are open. The piston-plunger moves from BEP to TEP and displaces the burned gases (the first factor). Simultaneously, high pressurized air, injected from the receiver through the open valve 102 also displaces the burned gases (the second factor). The clearing process provides the high-pressurized air, which was compressed in the previous stroke while the engine piston moved downward.

This combined action intensifies the exhaust process and increases the volumetric efficiency. The additional cooling (intercooling) of air by the water jacket of the receiver is the third factor. Thus the three joint factors improve the filling process (of the air in case of diesel, or of the mixture in case of gasoline engine) and increase the specific power of the engine. The combined clearing process ends when the exhaust valve is closed.

The joint compression process is shown in the FIG. 20C.

The exhaust valve 104 is closed and the air injection valve 102 is open. The engine piston continues movement, and, jointly with the air injection, increases air pressure in the cylinder because the air pressure within the receiver is greater than that within the combustion chamber. The joint compression process ends when the injection valve is closed.

The finish compression process is shown in the FIG. 20D.

The valves 102, 104 are closed. The engine piston continues compression. Before TEP, the pressure in the cylinder becomes the maximum. A conventional fuel injection system (not illustrated) provides the start of the engine power stroke. The working cycle ends after one rotor revolution.

Thus the two-cycle engine of the hybrid uses inexpensive four cycle engine cylinder head, with the intake valve functioning as an air injection valve. This valve replaces conventional two-cycle engine cylinder wall air ports, and improves the two-cycle engine operation. This solves the problem of boosting the two-cycle engine power by super high pressurized air injection and enables to realize a great potential possibility of a two-cycle engine—at least twice the specific power of a four-cycle engine with other things being equal.

The engine, compressor and pump operation is the function of the two independent arguments: first—the swash plate angle, second—the distance between the rotor centerline and the swash plate hinge pin axis. The first argument determines the engine, compressor and pump displacement volume. The second argument determines the engine compression ratio. The widely known engine compression ratio determines the kind of fuel (fuel octane rate) and determines a very important requirement: the engine compression ratio must be independent of the engine displacement volume change while the engine operates with the given fuel. This requirement executes in full the hybrid synchronize mechanism in accordance with the next proof.

The proof of the engine displacement volume changing independent of the engine compression ratio (see FIG. 21A, 21B).

The proof gives us:

-   1. The engine compression ratio is independent of the swash plate     angle     in accordance with equation (8). This is because both the engine     piston stroke     and the clearance δ is proportional to the swash plate angle tangent     (see equations 2 and 5). This provides the engine operation with the     variable displacement volume and invariable compression ratio during     the swash plate angle Θ alteration (moveable pin) while the swash     plate hinge pin is fixed (B=const). -   2. The engine compression ratio is dependent on the distance B     between the rotor centerline and the swash plate hinge pin axis in     accordance with equation (8). This enables the different kind of     fuel use and the engine transformation into an omnivorous engine by     means of the distance B alteration.     The example of the distance B depending on the engine compression     ratio:

Lets the engine with the distance between axial rod axis L=60 mm works with the compression ratio Λ=10 and the equation (9) gives B=36.7 mm.

Lets the other fuel requires the engine compression ratio two times greater with Λ=20 and the equation (9) gives B=33.2 mm.

This example illustrate that the distance B small change gives great engine compression ratio alteration. Also this example illustrates the effective and easy method of the engine transformation into an omnivorous engine by means of the distance B alteration (moveable hinge pin).

The FIG. 18A illustrates the minimum engine displacement volume in accordance with the minimum swash plate angle Θ incline. The FIG. 18B illustrates the maximum engine displacement volume in accordance with the maximum swash plate angle Θ incline.

The swash plate turn mechanism and swash plate turn hydraulic system realizes the possibility of the engine operating with the variable displacement volume and the invariable engine compression ratio while the swash plate hinge pin is fixed (B=const).

The swash plate shift mechanism and swash plate shift hydraulic system realizes the possibility of the engine operating with a different kind of fuel, and the engine becomes, in essence, an omnivorous engine.

The engine, compressor and pump variable displacement volume gives the additional ability of adapting the engine power to the automotives wider variable load and speed range.

The engine and compressor displacement volume simultaneously increase gives the additional ability of adapting the engine power to the automotives wider variable load and speed range.

The hydrostatic motor and stabilizer motor connection in series enable said hydrostatic motor displacement volume to control automatic by stabilizer motor inlet fluid pressure to maintain permanent independent of the engine load and cycle per min.

The engine, compressor and pump variable displacement volume provides of the engine operation with the minimum specific fuel consumption during the automotives wider variable load and speed range.

The FIG. 22A illustrates the compressor piston stroke F₁ and the distance between compressor and engine pistons change from G₁ to K₁ during the half rotor revolution. This distance change determines the compressor displacement volume and the compressor compression ratio in accordance with the swash plate angle Θ₁ incline.

The FIG. 22B illustrates the compressor piston stroke F₂ and the distance between compressor and engine pistons change from G₂ to K₂ during the half rotor revolution. This distance change determines the compressor displacement volume and the compressor compression ratio in accordance with the greater swash plate angle Θ₂ incline.

The FIG. 22B by comparison with the FIG. 22A illustrates the compressor displacement volume and the compressor compression ratio increase simultaneously with the swash plate angle and the engine displacement volume increase.

All these factors combine to provide use of the progressive hydrostatic transmission with variable displacement volume of the engine, compressor, pump and hydrostatic motor instead of widespread automotive engine and automatic transmission, thereby minimizing the weight, installation space, cost, labor and fuel consumption. Pneumohydraulic accumulator charging.

While the hydrostatic motor shaft is stopped the PHA fluid pressure low magnitude determines the signal from the fluid pressure sensor (not illustrated) and on board computer (not illustrated) automatic switches on the solenoid 368 of the distributor 364. The distributors 358 solenoid 362 is switched off. The fluid flow occurs in accordance with hydraulic diagram FIG. 18G during engine piston power stroke and in accordance with hydraulic diagram FIG. 18H during engine piston return stroke. The PHA charge provides the spin valve, which disc actuates the rotor by means of the intermediate shaft 198 (FIG. 5).

During the engine piston power stroke the pump supply goes to the PHA and spin valve with the distributor 364 provides fluid supply to the stabilizer motor inlet from replenishing system pump 68. During the engine piston return stroke spin valve with the distributor 364 provides the PHA fluid supply to the stabilizer motor inlet and simultaneously distributors 358 provides fluid supply to the pump inlet from pump 68.

Because the stabilizer motor intake during the half rotor revolution is only half of the pump displacement volume (stabilizer motor volume and pump volume is approximately equal during whole cycle) about half pump displacement volume of the fluid entered the PHA during one cycle (one rotor revolution). So the PHA fluid pressure increases during one cycle. The signal from the fluid pressure sensor switches off the solenoid 368, and switches on the solenoid 366 and the distributor 364 switches to the idling position when the fluid pressure achieves maximum. Thus the engine fast charges the PHA automatically. The hybrid solves the problem of charging a PHA automatically, irrespective of the parking time, even if the fluid pressure is greatly decreased. The starter pump 402 (FIG. 18) by means of the pedal 404 provides an opportunity to increase the PHA fluid pressure with muscle efforts in the emergency case. Thus the hybrid readies the engine for next high power, fast start.

The variable displacement volume of the engine, pump and hydrostatic motor providing the engine power adaptation to the wider variable load and speed range enables the hydrostatic motor and electric motor direct mechanically association. The hybrid system provides stand-by electric energy utilization by means of plug in during the electric motor in the generator mode charges the electric battery (not illustrated). So the hydrostatic motor 44 and electric motor 46 shafts connecting to one gear 352 (FIG. 18) by engaged and disengaged clutches 354, 356 provides joint and separate the hydrostatic motor and electric motor operation in either combination.

The gear 352 can be connected to automotive wheels by means of differential (not illustrated) and in case of both clutches disengaged the automotive can be braked, can free rolling and the electric motor in mode of the generator can charging the electric battery by means of plug-in. Both clutches engaged during hard acceleration from a stop and provide maximum power, in this case hydrostatic motor and electric motor work in tandem. This mode operation occurs when driving conditions demand more power, such as while climbing a hill or passing other vehicles. In case of hydrostatic motor's clutch engaged and electric motor's clutch disengaged the automotive drives engine by hydrostatic transmission. The case of hydrostatic motor's clutch disengaged and electric motor's clutch engaged provides possibility of the regenerative braking, the electric battery charging during the automotive deceleration and stand-by energy to increase. All this mode operation with engine variable displacement volume considerable decreases the fuel consumption.

All hybrid advantages enable us considerable to decrease the automotive fuel consumption.

The following illustrate the approximate fuel economy of the monocylindrical hybrid use in a car with the progressive hydrostatic transmission under city driving conditions.

Rate fuel Method of the fuel economy economy 1. All modes operation with the minimum specific 18%    fuel consumption 2. Direct energy transmission with the air intercooling 12%    supercharger 3. Engine shut down at every red traffic light 8% 4. Engine and progressive hydrostatic transmission lighter 7%    weight 5. Energy recuperation with smaller engine capacity 30% Total 75%

The monocylindrical hybrid with the direct energy transmission, variable engine, compressor and pump displacement volume and hydrostatic transmission energy recuperation enables us to achieve approximately 80 miles per gallon in city conditions and to maintain the automotive acceleration magnitude.

The monocylindrical hybrid enables at least:

-   using a two-cycle engine with either diesel fuel or two-cycle     gasoline engine. In case diesel is used, a conventional system of     the injection pump and the fuel injector into cylinder head (not     illustrated) are used. In case gasoline is used, a conventional fuel     injection system with spark plug into cylinder head (not     illustrated) is used. In either case a conventional throttle (not     illustrated) is used to control the amount of air entering the     intake line of compressor -   using conventional fuel, cooling, electric and other accessory     systems, this considerable decreases manufacturing cost -   using the additional engine cooling by the receiver water jacket     separately or jointly with the engine cooling system, or engine     cooling by air -   using the pressurized air in the receiver for other purposes, for     example, pumping more air into the tires -   using with various kinds of hydrostatic transmission such as     variable or fixed displacement conventional motor, closed or open     loop; and providing the cylinders of machinery work equipment with     high pressurized fluid -   using the installation in machinery with either orientation of the     engine cylinders axis: vertical or horizontal, or the either angle -   using various kinds of the swash plate turn automatic system with     the engine torque and rotor angle speed signal and with either kind     of the feedback: electric, hydraulic or mechanically -   using with various kinds of gaseous fuels such as propane, natural     gas, methane, hydrogen, etc. by means of simple swash plate shift     mechanism -   using the swash plate shift mechanism with automatic or button     control for the engine compression ratio alteration and either kind     of fuel utilization -   using the fuel spontaneous combustion (detonation) for more power     output per engine displacement volume thanks to the direct energy     transmission from engine piston to the pump plunger -   using the pump's rotor with lobes driving a compressor's valves both     the variable displacement hybrid and invariable displacement hybrid.

Thanks to the foregoing advantages the monocylindrical hybrid may be used in trucks, locomotives, boats, motor-cycles, aircraft, portable power systems, construction machinery, automobiles and other kind of the automotive and equipment.
